1.7147 (DIN 17210 : 1986-09) 1.7147 DIN 17210 : 1986-09 DIN 17210 : 1986-09 replaced by DIN EN 10084 : 1998-06 Replaced Germany 20MnCr5 ≥ -25 1)
1) Remark: The steel 20 MnCr 5 in opposite to 16 MnCr 5 is used for larger parts with higher core strength and advantageous toughness properties in the vehicle and mechanical engineering (e.g. gears, shafts, steering parts). The lowest application amounts to -25 °C, the best application up to 50 mm nominal size.
